, i RAZOR-STROPPING MACHINE.

Application led November 4, 1921. Serial No. 512,829.

To @ZZ eli/2.0m t may concern Be it known that I, CLARENCE E. SMITH, a citizen of the United States, residing at Peoria, in the county of 'Peoria and State of Illinois, have invented new and useful Improvements in Razor-Stropping Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to razor stropping machines, pertaining more particularly to a stropping device adapted to be held wholly in the hands of the user.

An object of the invention is to vprovide in a stropping device a body portion carrying a blade holder, and two reciprocating parts movable with respect to one another in op posite directions and with respect to the body portion, and adapted in their movement to cause the blade being sharpened to be alten nately and automatically reversed in position and moved against stropping members F carried by said parts.

Another object is to provide a stropping device wherein a body portion carrying a blade holder supports two members adapted to reciprocate in opposite directions andeach carrying a stropping portion, 4one .of the members being gearedto the other whereby in a movement of one of them a like move ment must result in the other but in an opposite direction, the movement of one of such members acting to rock the blade to be sharpened and carrying its edge against the two stropping portions, and to shift the blade whereby to realize thedesired diagonal stro-pping action. i

Another object is to provide a stropping device that will not be likely to get out of order, that can be easily operated, and will quicklysharpen a 'blade due toV the moveinent imparted 'to the latter. l

The stropping device includes a body portion comprises side members 1 having at opposite edges enlargements 2, Figure 3, said sides being connected by end members 3 forming a frame. Also connecting thesaid side members vat one side of the frame is a part t, Figures 4 and 5.

Engaging the enlargement 2 at one side of the said frame is a portion 5, constituting a slide, whose edges are turned inwardly to en close said enlargements, as most clearly shown in Figures 3 and 4. Secured upon one of the turned edges is a toothed raek 6 whose teeth mesh with those of a pinion 7 rotatable upon a stud S exending from one of the side members 1 of the .described ybody portion. The opposite ends. of the slide 5 areleacli provided with a flange 9 extendingsubstantially at right angles to the plane thereof in the direction `of the body portion and a stropping portion 10 such as leather, for eX- ample, is stretched from one to the other and secured at its ends thereto.

Engaging one yof the enlargements 2 opposite those engaged by the slide 5 just described is the flanged edge 11 of a frame 12, the opposite edge or said frame terminating inside the opposite enlargement 2 or in spaced relation thereto. This frame likewise has end flanges 13 corresponding to the flanges 9 of the side 5 'and a stropping por tion 14 is stretched between and is secured at its ends thereto.

15 is a channel portion engaging the remaining free enlargement 2 and slidable therealong. It has a depending .arm 15 adapted `for rocking a yblade holder to be described.

16 is a plate corresponding tothe slide 5 whose edges are turned inwardly to embrace. the flange 11. of the frame 12 and the channel portion 15 as clearly kshown in Figure 3. Said plate is secured to the frame 12 by bolts 1T, oikexample, which extend through both near their ends, Figure 2. The said plate 16 and frame 12 constitute a second slide which includes a toothed rack 16 engaging the pinion 7. y y

Depending from the said plate 16 is an g ign abutment 18 carrying a spring 19 adapted to friotionally engage the said channel portion for a purpose to be explained.

Mounted upon the part 4 connecting the sides 1 of the body portion, Figures and 7; is a blade carrier comprising end plates 20 and a bottom Connecting portion 2l, the latter being pivoted at 22 to said part iso as.4 to

swing in a plane parallel to that in Which the, body lies. Extending between and secured to the end plates 2 0 are members 24 which are spaced trom one another in a direotion perpendicular to the plane of the said body portion a distance substantially equal to the distance between the stropping portions l0, 14, Figure 5, the said portions, in their travel to be described, moving upon them.

Each ot the said end plates 20 has a vircul'ar openingI thereinY and one of them. receives a disc 25 outside of which. Figure "i, is a plate 26, secured thereto and having; an extension 27 provided with pin 28 which engages in a slot Q9 of the arm l5. depending trol-n the channel portion ln the openingv ofthe other end plate Ztl is a disc made up oit two halt portions 30, 3l., Figure 8. spaced from one another to. leave a slot 32 therebetween. The portions are secured to a plate 33 having' a-slot 34- therethrough ot al Width sucient to admit a razor blade.

Also. the end plate itself`v has. a slot 'for the same purpose Wit-h which said slots 32 and 34E Can be brought in register. The blade supporting device consists oil- ,ivo spaced strips 36, attached at one ot their ends to the dise 9.5 at one end of the carrier and at their other ends to the halt dise B0 at one side ot the slots 8e, Fleurie 8. and ot Carrier consistingof a sti-r 3T ot n width no greater thanv the diameter ot the disc made up of the halves 30.k 3l, so that the Whole can rock Within the openings in saidV end plates 20. @ne end. of' the strip 37 is bent at right angles to its plane. into a head 3S. a. shank 39 being; formed betWee-'f-,i the head and the stripI bv reducing the Width thereof, allowing it to. exten-tl bet-Ween ther strips 36;v the strip 37 lying at one side of' the strips 36 and the head at the other, thus. maintaining' the named. portions in assembled. relation.

The said strip 37 is provided with studs 40,01?, any other means to refeive and hold the razor blade. The. strips and strip 37 are a snilicient dista-noe apart to admit the razor blade which is. Wafer thin. said blade being placed; upon the said strip after pulling the latter outward(r` Figure T. ThenE pushed baekf between tlie end. plates 20 the blade is. securely ymounted and' may roolrivith. the oanrying parts Without chanee ot' becoming displaced.

It is observed that since the plates 26 and 13S rarrying these dises l end plates 20. and that th rips 36 connect said discs. the rocking' structure thus Created Cannot in :in v ivay leave the end plates The dependingV arm l5 oit the channel portion l5 When given a longitudinal movement through.v the shifting' in both directions ot said channel portion inrparts a vibratory movement to the plate 26 through the pin 23 by which the razor blade is rocked first inl one direction. and then in the other. carrying. its edges against the stroppingY portions so that each side ot. the blade at bothr edges can be stropped, it being` observed that the members 24 torni a backingv for those portions ot the stropping `portion with which the blade edges have contaot.

In addition to rocking the blade in the manner described the frame/made upoit' the end` plates 20, said members 24. and the poe tion 21 is made to, swing parallel to the stroppingrV`vr porti-on upon the pivot 221 in and due to, thel movement imparted to, the said plate. 26, snob movement beingl-iii31. i.,tedz by pins. or stops al extending troni the sides l of the body portion.l These sto-ps are spaced trom one.. another, one lying.- aty each sideot the said; frame.

rllo operate the device the slides 5 and 162 are `Qnhsped, in the hands and shift-edi iu opposite dii-'eotions Due to the tact that the pinion 7 is carried on the body portion and the toothed racks G, 1.6. engageV it, the slides more in unison. to the same extent and maintain acertain .relation to the l'iod-y portion at all times.

'Thespring lf) described has Constant 'frictional engagement with the channel port-.ion l5v so. that. in each shittingY movement of the said Aplate L6 the portion 1 5 is Carried n'ith it farvas the pins 4&1; will. permit. the blade carrier to swing. the pleite l@ com.- tinuing its movement with respect to the said portion. That to say the initial inoif'emeiit ot the plate LG shifts the. por* tion l5, rot-.king the blade to one limit of its. movement (Contact of blade edge-With the strom 'ngz portions) 'followed by shittingthe blalecarryingV structure on its` pivot 2 2 to plaoethe blade edge; in a diagonal position with respect to the. stropping portion. the plate Conti-inning its movement. in the direction imparted. with respect tesa-id portion l5. V

LAL reversal oit inoveifnent of the sl'les re iferses the blade position both as tot contact with the stropping; porti-ons and the diagonal position with. respect thereto.

The device. is simple in;r its appointments. easily operated. the operation is positive, the parts Cannot readily `@et out ot order, the diagonal stroppingI is-.r'eali- Zed in ai most. perfect manner, and the device takes up but small space in a travelers hit and cannot be damaged in anyway since the stropping portions are fully enclosed and protected when the ends of slides and body portions are brought flush with one another in the closed position as shown by dotted lines in Figure The pinion and toothed racks positively prevent movement ot either slide except in direct relation to one another to the end that there can be no danger of shifting either of the stropping portions in a direction to carry it against the blade in a direction that might injure it. In other words the travel of the stropping portions is and must be always away from the cutting edge of the blade. Preferably th-e {ia-nged edges of the slides are knurled to furnish a grip for the hands as an aid in operating the device.

The compactness, rigidity and strength of the device is notable and appealing. W'hile I may make slight changes in the construction and arrangements of the parts of the device they will be such as will fairly fall within the invention and the appended claims.
